But news that the bizarre food is actually good for you has led to a boom in orders for one butcher famed for producing some of the best blood sausages in the world.

Charles Macleod Butchers in Scotland's Western Isles has seen the demand for its iconic delicacy increase eight fold in the last few days with orders coming from as far away as London.

Replacement: Black pudding may replace previously popular foods like avocados

The Western Isles is famed for producing some of the world's best black pudding. In 2013 Stornoway Black Pudding was given the same protected status in Europe as champagne.

Lorna MacLennan, a director at the butcher shop, told the MailOnline: "I think it is an interesting one because it is not always classed as a health food given the ingredients, but it is actually packed with iron and protein so it's quite nice to see it is being recognised for its benefits.

"Traditionally in the Hebrides it was a real staple on every kitchen table because they want to use every part of the animal traditionally and black pudding was a great way of using up some of your by-products.

"It is low carb, high protein, no sugar and you don't need to eat a lot, it's very filling, and you get your iron with just a small portion."
